Although its a common complication ofdiabetes, hyperglycemia can happen to anyone.

If left untreated, high blood sugar can lead to hyperglycemia-related seizures.

About 25% of people with diabetes will experience seizures.Most often, these are because of low blood sugar.

However, if left untreated, hyperglycemia can also cause seizures.

Learn more about these seizures and how to prevent them below.

Types of Hyperglycemia That Cause Seizures

Two types of hyperglycemia can cause seizures.

This is also called hyperosmolar hyperglycemic syndrome (HHS).

With this condition, blood sugar levels are up to 10 times higher than healthy levels.

NKH occurs most often in older people with throw in 2 diabetes.

Ketotic Hyperglycemia

The second pop in of hyperglycemia that can lead to seizures is ketotic hyperglycemia.

This is most common in people withtype 1 diabetes.

When blood sugar is elevated, the body cant use it for fuel.

Instead, it starts burning fat.

As fat is burned, it releases chemicals called ketones into the bloodstream.

People who experience DKA are at higher risk of seizures.

This can cause the brain to short circuit, leading to a seizure.

Its best to intervene with high blood sugar before your glucose becomes high enough to lead to a seizure.

However, oftentimes people dont notice the symptoms of hyperglycemia until a seizure is imminent.

Hyperglycemia-related seizures can last for seconds or minutes, and always warrant medical attention.

Hyperglycemia, particularly NKH, can have complications outside of causing seizures.

Recognizing these can help you identify NKH and possibly help you avoid a seizure by seeking treatment immediately.

Remember that NKH is a potentially fatal condition that requires medical attention.

If you experience a seizure, it indicates that your condition is severe.

Hyperglycemia can have very severe, even fatal consequences.

It can also lead to long-term health complications.

Prevention is truly the best medicine for hyperglycemia-related seizures.

However, sometimes hyperglycemia or NKH can occur suddenly.

These conditions can be brought on by stress, infection, or illness.

Always reach out to your healthcare provider if you suspect you might be experiencing hyperglycemia.
